How to overwinter blue-green adenia
Winter watering
Cut watering right back — blue-green adenia uses far less while growth slows, and cold, wet compost is the usual cause of winter root rot. Stop feeding until spring.
The mistake that kills blue-green adenia in winter
Watering on the same schedule as summer. In winter that keeps the roots sodden while the plant is barely drinking, and blue-green adenia rots from the base.

Overwintering blue-green adenia — FAQ
Does blue-green adenia need to come indoors for winter?
Blue-green Adenia is hardy to roughly USDA zone 10 — winter lows around -1°C. That means it will not survive frost and needs to come inside. Blue-green Adenia is frost-tender, so overwintering means bringing it inside and letting it rest rather than pushing it to grow. Move it indoors well before the first frost, give it the brightest spot you have (light levels indoors drop sharply in winter), and keep it away from both cold window glass and hot radiators — the swing between the two does more damage than the cold itself.
When should I move blue-green adenia for winter?
Bring indoors when nights start dropping below about 10°C, ahead of the first frost.
How often should I water blue-green adenia in winter?
Cut watering right back — blue-green adenia uses far less while growth slows, and cold, wet compost is the usual cause of winter root rot. Stop feeding until spring.
